Curious about this chicken...

I meant to ask a few years ago but I always forgot... we received 36 hatching eggs from a hatchery 2 years ago, with maran eggs and a collection of "random extras" to make up for any eggs that didn't hatch. Well, in the end, only 14 eggs hatched, 2 died, and we ended up with 6 roosters and 6 hens. We had 3 maran roosters, and 2 maran hens. One of the maran hens died.

We also ended up with three hens - two are like the one in this picture, and 1 was a grey one exactly like them who died.

I'm not exactly sure what they are. Although they do look a bit like some easter egger pictures, I'm not completely sure. They both land off-white (tannish) eggs, medium sized, average quantity. They are fairly calm, never broody, and love the cold but hate the heat.

Could be a crossbreed, considering the 'outcome' of the hatched chickens (the other hatchlings included english game batam rooster and pullet, a coloured dorking mix rooster, an unknown mix rooster..)
